I love to think that you pore over each and every word I write. I also realize that you have a life. Feel free to skip any information that seems far afield from what you need to know. The stuff that no one should ever really have to know (but which is nonetheless utterly fascinating) is clearly labeled with a Technical Stuff icon. You’ll also run across some bonus material placed in a sidebar — a gray shaded box — that I fill with cool-to-know-but-not-imperative stuff.
